I would like to split the HTTP open_timeout into two components:
  connect_timeout and dns_timeout

connect_timeout would be trivial to implement

Like akr said, it's not an issue now.  The performance issue is that
getaddrinfo() in standard C libraries doesn't provide configurable
timeouts so we have to use the nasty timeout library that spawns
a thread every time we need to do a DNS lookup...
